My question is: can I install phpbrew with an existing PHP version?
You'll have to have an existing PHP before you start using PhpBrew because it's written in PHP.
If yes phpbrew can manage this version as the phpbrew installed versions?
PhpBrew cannot manage the system PHP version. You can only switch PhpBrew off to start using the PHP version.
